After upgrading to the latest version, my web WhatsApp stopped working.
I use my iPhone to scan the QR code. It reads but after a few moments he reads again and finally, nothing happens.
I get this error message - " database error occurred on your browser. Please restart your computer and relink your device."
I have restarted my MacBook Pro a few times but getting the same result. I am using Big Sur the latest version on my mac and likewise the latest os on my iPhone.
When I use the private window, it works. I have also cleared all my cache a few times and disabled all extensions but still the same result.
I have also disabled the Beave Shield and had the same result.
It is working on my end. You seem to have done everything on your end to make it work. Still create a new test profile from top right-hand corner hamburger menu. In this new profile, do not add or change anything, then see if whatsapp web works normally.
Is your macbook pro on the new M1 chip. I have read that brave (or other browsers) having problems on m1 chip.
Had the same problem on my Linux machine.
Here is how I solved it. Like @chh_68 said, make sure you are logged into a profile.
On the hamburger menu (top right)>> create profile, make sure the profile is visible.
It should now work
That the only thing I changed on my computer.
